Brumby Christine as she appeared when taken off her soft coastal habitat (top two photos) and after three months in hard substrate desert terrain (bottom two photos), as part of an experimental switch between herds in Australia. Her hoof wear was 3x that of another mare and she lost considerable condition (weight) during the period. Researchers decided to remove her from the experiment even though her feet, as shown, seemed markedly more healthy and robust by natural hoofcare parameters but welfare was of equal concern.

The Australian Brumby Research Unit has completed an experimental transfer of horses between different terrains, over 1000 miles apart. The results were recently announced after massive amounts of data, including hoof growth vs. wear measurements, were compiled. The purpose of the switch was for scientists to observe and document the transition that horses go through when environmental conditions change.

The cover of the Proceedings of the 2009 laminitis conference is a compilation of images of one foot of a chronic laminitis case from the University of Queensland in Australia. The foot's CT scans were converted to 3-D images using Mimics software and the expertise of Dr. Simon Collins of the Animal Health Trust in Newmarket, England. (Double-click on image for a larger view in a new window, but sorry that the web requires a low-resolution version of a very high-resolution form.)

The heightened visual aspect of the exciting biennial conference, which will be held November 6-8 in West Palm Beach, Florida, may lie in the technology side of things, but the impact will be an eyeful that everyone can appreciate.

Leave it to Dr. Chris Pollitt (photo inset at left), assistant director of the conference, to bring the latest and greatest technology to the conference and to enhance his presentations.

The new software is called MIMICS; it is made by a Belgian company called Materialise NV. In a nutshell, MIMICS converts CT scans into three-dimensional forms. I've also seen it used to model a nasal cavity for a surgery case at Cornell's vet school, and for a comparative study of the soft tissue structures of equine feet at Auburn University. Dr. Pollitt says that MIMICS software is used extensively for human skeletal reconstruction surgery and prosthetic implant design and simulation.

"Suddenly I can 'see' an individual horse’s foot from all angles and can virtually dissect it on the computer monitor," Dr Pollitt wrote in the Proceedings.

MIMICS was introduced to Dr Pollitt and to the world of laminitis by British hoof anatomy researcher Dr Simon Collins. Dr Collins will be in Palm Beach to explain how he uses computer modeling in his work at the Animal Health Trust, where he collaborates with lameness experts Drs Rachel Murray and Sue Dyson. His images will be dazzling.

Dr Pollitt wrote in his introductory essay in the Proceedings, "Analyses of feet with chronic laminitis clearly show that distorted tubular hoof growth, lamellar wedge formation and solar loading of the distal phalanx are relentlessly destructive to bone. It behooves laminitis caregivers to understand the unmitigated, severe chronic process and develop proactive, early intervention strategies that will measurably arrest the process. MIMICS in the hands of laminitis scientists will aid this process."

Does anyone besides me see great irony in the way that Dr Pollitt over the years has created stunning visual images of the terribly destructive disease of laminitis? The quality of his images is always worthy of Scientific American or National Geographic and yet the subject is the disease we all dread. Thanks to his artistic eye we all know what laminitis looks like, even though it's the disease we'd most like to see wiped off the equine map.

NOTE: The deadline for registration for the conference has been pushed back to September 28th, since the mail has been so slow in getting the brochures and registration forms to everyone. Brochures were sent to all subscribers to Hoofcare and Lameness Journal. Also, a reduced rate for two-person registrations has been added. Visit www.laminitisconference.com for more information.

Wherever you are today, you are probably a long way from Stanley Vasques. But we all share an interest in horse hooves and their care. The only difference between most of us and him is that Stanley will wake up this morning and go to work in one of the most beautiful places in the world.

Stanley has been shoeing horses on the Hawaiian island of Kauai for more than 40 years. An article about him was published in the island newspaper, and I thought you might like to get to know Stanley and see a little bit of his world.

Click here to read an article about someone who will wake up in paradise this morning and go out and shoe some horses.

A last-minute addition to the 2009 NEAEP conference program is farrier Patrick Reilly from the University of Pennsylvania's New Bolton Center. Pat is filling in for farrier David Farley; both Dave and Pat are on the board of the new organization, which has both farriers and veterinarians among its members.

Patrick's lectures will include interesting studies and observations of hoof balance. In the video clip above, you will see that he has been documenting comparative solar forces on the hoof during athletic activities. This video clip shows the extended trot, which will be compared to a working trot in both a straight line as well as on a 20-meter circle. Pat also has some interesting measurements of the solar forces during jumping, and a comparison of differing density rim pads during jumping.

Patrick's videos and the use of pressure-sensitive data collection media give him some opportunities to make observations that bring up plenty of questions. For example, the same horse might land toe first in one gait (such as the extended trot), but land heel first in the regular trot. Also, a horse might land laterally on one footing, but lands evenly with the same trim on another.

Data from the hoof is transmitted directly, rather than through a pressure-sensing plate in the ground

The rider in the video is Patrick's wife, Karen; the flashy horse is her own; they just won a national young horse title last month. Congratulations!

Don't call the office this week. Hoofcare and Lameness will be on location at the first-ever conference of the Northeast Association of Equine Practitioners (NEAEP) in Ledyard, Connecticut. The new NEAEP organization is kicking off its public persona with a double-barreled lecture series from Wednesday through Friday. One lecture hall is podiatry only, while the other covers a range of veterinary topics, including equine sportsmedicine.

Chances are, you'll find me in the podiatry lectures. The NEAEP has brought together a great group of speakers--including Robin Dabareiner, Melissa Fagerlin, Ian McKinlay, Scott Morrison, Scott Pleasant and Patrick Reilly--and filled a trade show with exhibitors.

I will try to keep the blog updated from Connecticut, but if you are planning to attend--and I hope you are--please stop by the Hoofcare booth in the trade show and say hello!

Registration will be available on site; details are at www.neaep.net. See you there!

PS I chose this nice old illustration as our company's booth logo for this event because it is so old. It dates back to a time when farriery was veterinary medicine, and the art of bandaging a horse was an example of one of the many arts of farriery. NEAEP is an organization comprised of both veterinarians and farriers (and other horse health professionals) and I am looking forward to working with this organization for many years to come!

Today's a dark day in New York history, and the day when horseshoes made the headlines of the New York Times...and it wasn't good news.

It was 89 years ago today that a horse and wagon ambled down Manhattan's Wall Street and exploded into bits in front of the Morgan Bank in an attempt to assassinate financier J.P. Morgan. Instead, the heinous act killed 38 innocent people and injured at least 300 more.

When the 9/11 tragedy struck in 2001, few people were familiar enough with New York history to know that it was not the first terrorist attack in lower Manhattan on a September day. The anarchists had tried it first.

All that was found of the wreck were the horses' hooves--all four showed up mysteriously in a neighborhood church. The police combed all the stables and blacksmith shops in New York City looking for clues…by trying to identify these horseshoes. Because the farrier had stamped the initials of his two unions ("JHU" and "NOA"), the NYPD detectives, Department of Justice (this was before the FBI) and Secret Service hoped the shoes could be traced back to horseshoers who belonged to both unions, until the detectives found out who had actually shod the horse.

To quote from the December 1920 edition of the Horseshoer’s Journal: "Of course, no onus is attached to the shoer, but the link of evidence is of greatest importance. (The horseshoer’s identity) lead to the arrest of the party responsible for the awful calamity which shocked not merely the whole of America, but the entire world."

This is one of the hind shoes taken off one of the hooves of the dead horse. The initials stamped in the shoe indicate union membership as a protection mark. Another union farrier might help out and reset the shoe if it was loose, but they would honor that horse as being shod by the brother. This was a code of honor among union horseshoers.

The headline in the New York Times read "200 Detectives Canvass Farrier Shops for Clue to Identity of Bomb Driver". The police began by enlisting their own farriers to analyze the horse shoes and tell them everything they could about them and the horse that might have worn them.

Finally the shoes were traced to the farrier shop of Finnegan and Kyle at 85 New Chambers Street and a farrier from the Bronx named John Heggarty.

How did Heggarty pick the shoes out as his? How would a farrier know his own shoe? Heggarty told the Times that he "found on the fore shoes the horizontal line just above the heel clip which he always has put on his handiwork as the sort of secret identification mark which all horseshoers use, largely for the purpose of know their own work in case of complaint. Haggerty is a non-union man and called attention to the absence of the JHU...from the front shoes, though they were on the hind shoes.

What's going on at the site of the shoeing forge at 85 New Chambers Street in Manhattan today, thanks to Google Maps

Unfortunately Heggarty couldn't (or wouldn't) remember who brought the horse in, and said as way of explanation that he shod eight to 12 horses a day. The shop is near the foot of the Brooklyn Bridge and the Fulton Street Ferry, so police speculated that the horse had come from off Manhattan.

Interestingly, farrier unions are among the oldest in America, and in the 1920s, farrier unions espoused what sounds today like extreme left-wing rhetoric. An editorial in the same edition of the Horseshoer's Journal calls on local unions to "oust their Bolshevik members". Was Heggarty a Bolshevik sympathizer? Did he re-use someone else's shoes who was a union member for the hind feet of the horse? What happened to him?

This story raises many more questions than it answers, but it offers many great history lessons. I highly recommend the archives of the New York Times, which are available online, or interested blog readers can email me or leave comments to continue this discussion.

In Boston also in 1920, the JHU struck against the Master Horseshoers Association; employee farriers (journeymen) walked out of the large city farrier shops owned by the powerful master farrier owners. The city stopped.

The year 1920 was also the height of the horse population in the USA: an estimation 25 million horses, perhaps even more, were hard at work in the cities and on farms, compared to less than 10 million today. (Estimates range from 6 to 9 million horses.)

To this day, the crime has never been solved, but the scars on Wall Street have never been repaired. They remain as a solemn reminder of the day a horse and wagon became the first suicide bombers in the neighborhood. But not the last.

A 9.2 hand, 12-year-old spotted pony named Firefly suffered from overgrown feet and laminitis in England in April 2007. She couldn't walk properly, but her owner refused to have her cared for, nor would she sign the pony over to the World Horse Welfare. A court case ensued and the owner lost her right to own horses for two years.

Here's Firefly in September 2007, on her way to full recovery and adoption to a new home. The research project funded by WHW at the University of Liverpool suggests that it is difficult to assign an objective body condition score to ponies using the system designed for larger horses.

Researchers at the department of clinical science at Britain's University of Liverpool, with support from the World Horse Welfare charity, presented new research at the annual convention of the British Equine Veterinary Association(BEVA) last week.

The question: how accurate is conventional equine body condition scoring for weight loss management when the equine being evaluated is an overweight pony?

During this time the ponies' weight change, health parameters and behavior were monitored. All ponies remained healthy throughout the whole trial and an appropriate and safe rate of weight loss was achieved.

Clare Barfoot BSc (Hons) RNutr, registered nutritionist and the research and development manager for SPILLERS® (British horse feed company) explained: “Body weight decreased at a steady rate. However, despite significant weight loss, the body condition scores of the ponies didn't change. This highlights the concern that body condition scoring may not be the most effective way to monitor early weight loss in ponies.”

Even in this well-managed study, the feeding activity of the dieting ponies was decreased by 74 percent compared to ad libitum intake, highlighting the need for a practical feeding system that is both effective at managing weight loss but is sensitive to behavioral needs.

The WALTHAM® Equine Studies group was closely involved with this study as it has been with other groundbreaking work on equine obesity, such as showing that an obese body condition score was associated with increased insulin resistance back in 2003, and developing the cresty neck scoring system.

In response to the study, the research group is in the process of developing a new condition scoring system designed specifically for ponies. “This will involve validating the relationship between actual measurements of body fatness and the external appearance of the pony,” said Alex Dugdale, lead researcher for the study at Liverpool University.

Jason Wilson-Maki is the first resident farrier at Texas A&M University College of Veterinary Medicine's Large Animal Hospital.

The following article is provided by Angela Clendenin of Texas A&M University. I don't think I know Jason Wilson-Maki, but wish him the best of luck in his new position and congratulate A&M for taking the important step of hiring a full-time farrier. Photographs were also provided by A&M.

COLLEGE STATION, TX –A certain specialization that is often overlooked or unknown by many people today is that of a farrier. A farrier’s job is to provide shoes for horses, and to work on their hoof problems. The Texas A&M College of Veterinary Medicine & Biomedical Sciences does a lot of work on lame horses, and a big part of treatment for horses’ hooves often requires therapeutic shoeing, and a specialist who knows what to do.

“For years, Texas A&M has had a farrier contract on an 'as needed' basis,” said Dr. Kent Carter, Professor of Equine Lameness and Chief of Medicine at the Texas A&M College of Veterinary Medicine Large Animal Hospital. “The problem with this type of contract is that we don’t always know when we are going to need a farrier and that makes us unable to provide full service to our clients.”

One year ago the faculty decided to do more towards pursuing a full time farrier to provide a better resource for our clients as well as a better teaching and learning environment for professional veterinary students.

“We set out on a national search for a full-time farrier and received a tremendous response,” said Carter. “There were 30 or 40 applicants who were narrowed down to 12, and finally we interviewed 5 of them. Jason Wilson-Maki had the most outstanding interview.”

A native of Ohio and a 1997 graduate of the Heartland Horseshoeing School, Jason was qualified for the job because of his previous experience and teaching. He also has a double certification in the American Farrier’s Association and the Farrier’s Guild (Guild of Professional Farriers). He showed great enthusiasm about horses and teaching during his interview and began work at the Texas A&M College of Veterinary Medicine during October of 2008.

Wilson-Maki feels that one of the greatest benefits of working as a farrier at a vet hospital, as opposed to being self-employed, is that working with so many veterinarians eliminates the guesswork, and is of greater benefit to the horses.

“Having a diagnosis and a prescription reduces the amount of trial and error required to improve an animal’s performance or soundness” said Wilson-Maki. “Moreover, the direct communication between the clinicians and myself benefits the animal by reducing the risk of a miscommunication. If I have any technical or application concerns, these issues can be discussed. This facilitates an individualized, comprehensive treatment for the animal which accomplishes the goals of the attending clinician and stays in step with the fundamental principles of sound farriery. This team approach is a great joy for me.”

Since such a huge part of an equine veterinarian’s career has to do with providing the physical skills needed to handle problematic hooves, Wilson-Maki’s expertise has taken the veterinary medical students’ education to the next level.

“It has been such an enjoyable experience interacting with the vet students,” said Wilson-Maki. “It is great to be able to see the light go on in their heads when applying certain aspects that they have been taught, but have not been able to apply until now. The students are constantly challenging me with questions that I must sometimes pause to think about the answer! Working at the CVM has truly been the best experience of my life.”

From enhancing veterinary medical education to providing value added service for clients, the farrier service at the veterinary medical teaching hospital has given the clinicians at the CVM another tool for helping their patients.

“Having a full-time farrier on staff has been extremely beneficial” said Carter. “We are able to provide a more consistent and thorough job for clients, as well as a better learning experience for students pursuing their veterinary degrees.”

Weathervanes, that is. They are one of the best ways to make a statement. A silhouette against the sky can be seen from afar and a good blacksmith can create a work of art to go atop a barn's cupola, a vet clinic, or a mobile home. Or a car dealership, clam shack or tipi.

It takes the observer's eye up to the sky and there's something uplifting about that, it more ways than one.

I just wish it wasn't so hard to get a good photo of a weathervane! It seems like there are always power lines or something in the way, or I can't get a good angle from the ground.

This is my new favorite weathervane, captured on film by Dave Angood, who tells me he found it atop an old barn inside some fortress-like gates near Swaffham in Norfolk, England. He allowed me to share it with Hoof Blog readers. I kept staring at it for the longest time this morning.

It reminds me of the beautiful weathervanes made by a farrier and heavy horse expert named Richard Gowing in England. If Richard didn't make it, surely his past work helped inspire it. Our friend the late Edward Martin from Scotland made beautiful weathervanes too.

Weathervanes carry some responsibility, of course. They have to be aligned with the earth. In our little seaside village, my salty old neighbor died and left a provision in his will that money from his estate be used to get steeplejacks to come and re-orient the weathervane on top of the church which, over the years, have drifted out of alignment.

It really bothered him. He saw the vane as a tool to check the wind as he drove toward the harbor each morning rather than the beautiful ornament on the church that the rest of us saw.

It's fixed now.

What--and where--is your favorite weathervane?

Thanks to Dave Angood for his hard work in getting such a good shot of this beautiful weathervane. Dave's trying to find out more about it and I'll add more details if he reports back.

British Columbia veterinarian Geoff Gaunt was strolling down the narrow streets of Florence, Italy on his summer vacation when he looked up...and smiled. He snapped a photo for the farriers back home, and I'm sharing it with you all, too.

Take a really close look at this "shoe". What looks at first glance like a Natural Balance shoe is actually a urethane hoof application created on the foot by injecting Vettec Adhere material into a mold. Vettec Superfast is sometimes also used, but Derek said that in this particular shoe, Adhere made the shoe more flexible.

Here's the ground surface of a six-degree short-heart bar, made for a horse with a fractured navicular bone.

A new shoeing technique developed in Dubai by South African farrier Derek Poupard is offered for your comments. In addition to the photos above, we have a short video showing how the mold is applied and the material is inserted, and the removal of the model to reveal a "shoe", if you want to call it that.

"This is so new, I only put my first one on 4 months ago, and after doing hundreds I now feel it is time to expose it," Derek wrote in an email. "I have only shown it to a handful of farriers here and right from the word go they embraced it and it is very rewarding to see their response as they peel of a mold seeing the perfect shoe. They all describe it as a revelation and every time they use it, it gives them the same feeling over and over again."

This has been a big year for plastic and composite horseshoes. First Curlin won the great classics of his four-year-old career last fall wearing square-toed Polyflex shoes of polyurethane. Then Steffen Peters and Ravel won the World Cup of dressage wearing plastic Eponashoes. This week, the venerable Horse and Hound news magazine from London carries a feature article touting the popularity of plastic shoes, especially those designed by our friend, the clever Andrew Poynton, who has expanded his moldable Imprint therapeutic plastic heartbars into sporty new models for competition horses.

And now we have the possibility of design-it-yourself hoof molds to make not shoes, exactly, but something else, a hybrid lighter and perhaps more cohesive with the foot than a separate shoe attached by nails would be. While steel and nails have their advantages too, this new technique may find a niche of its own, or become a platform for inventors or farriers and veterinarians faced with challenging hoof injuries or deformities.

This second video was made a while ago by a Dubai television station that visited the royal stables where Derek works. It's a nice view into the facility and shows Derek's previous traditional use of glue-on shoes on a Thoroughbred racehorse.

Eventually, Derek's molds will be available for sale, I'm sure, but in the meantime, the floor is open for comments. He's a world away from almost all of us and would like to hear from you, I'm sure.

Some American readers may remember Derek from his time spent living and shoeing in Virginia. He has been featured in Hoofcare and Lameness Journal in the past but when he left the USA several years ago, we lost track of him. A royal farrier shop in Dubai is an interesting place for him to be found.

New shoes continue to come on the market or be passed around as prototypes. This process is quite unique, though, and while it seems cumbersome and awkward at this stage, it is sure to improve and become more streamlined.

The go-go girl herself takes to the track at Saratoga on Saturday. Miracle filly Rachel Alexandra skipped the Travers Stakes for three-year-olds in order to challenge older males in the shorter mile-and-an-eighth Grade 1 Woodward Stakes.

Expect Saratoga to be the site of the biggest traffic jam in New York State since Woodstock. Really. Since the race is not televised, the only way to witness this historic event is to Be There.

My guess is that there's a pool somewhere on what the gate attendance will be. Perfect weather is forecast.

Will someone who has TVG or HRTV or OTB call me and hold the phone so I can hear Tom Durkin call the race? I'd like to hear history firsthand, even if I can't see it.

Ace photographer Sarah K. Andrew of Rock and Racehorses just uploaded this nice shot of Rachel leaning into her bath sponge so I thought I would share it with you all. Thanks, Sarah, for the perfect timing and the beautiful photo.

Win or lose, Rachel Alexandra has made this an exciting summer. Right about now, she's camped out in the detention barn so she knows something is up. What is up is that New York and the nation has fallen in love with this horse and what they think she can do, who they think she is, and the time is just exactly right.

I don't know if this will be her last race or not but with each and every race, work, and schooling session she went through at Saratoga, I marveled that she's been my good news story of the year. And I want her to stay that way.

I had an idea for this blog post: Everyone turn the sound off when you watch this video, and then you won't be influenced by the location. Because for nine minutes and thirty seconds, this video takes you into a universal setting. This shoeing forge could be in Colorado or Sweden or Turkey or Japan or New Zealand, with few changes. It's a pretty universal scene.

However, the sound is very nicely recorded and adds a lot; after a while, the apprentice's voice comes on and you'll hear what it's like to train as a second-year apprentice farrier in remote Donegal, on the northwestern edge of Ireland.

I play a lot of games when I watch farrier videos (and I watch a lot of them). I love to watch the background activity (and give bonus points for multiple dogs) and in this case, the shoe pile jumps out of the background and dominates the whole forge. Obviously they aren't worried about earthquakes in Donegal or else John and Heather will be buried in old shoes some day.

A game I like to play with non-US videos is to try to pick out the countries where tools and clothing and shop decor were made. In this video we see Kevin Keegan's ubiquitous Hoof Jack--is there a country on earth that the Hoof Jack hasn't conquered? I'm staring at one in my office right now as I write this.

Readers: send in photos of your Hoof Jacks in a native setting showing what it's like in your part of the world where you live and work. Just make sure the Hoof Jack is in the photo somewhere. I'll post them on the blog.

I wondered where the loop knife came from: Canada? Australia? Montana? Germany? and John's apron has a made-in-the-USA look to it. The "w" on the shoes is the forge is a giveaway that they are by Werkman and from Holland.

That's just a start, you can take it from there. Many thanks to the gentle director and editor who refrained from a voiceover narration, intro music and splashy graphics. They had the good sense to just let this scene speak for itself so those of us who know what to listen and look for, can. And I hope you will.
